Fluorine and bromine have 7 valence electrons and hence their properties are similar. Neon has 8 valence electrons and the properties are different from that of fluorine.
Fluorine is more similar to bromine than it is to neon. Both bromine and fluorine are halogens with 7 valence electrons while neon is a noble gas with 8.
Something more reactive than bromine. Chlorine or fluorine would do it.
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
The thing that makes fluorine so reactive is its electronegativity.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
Fluorine, Chlorine, Iodine, and Astatine. You can find this out just from looking at a periodic table. (Electrons are what create the properties of atoms). Because of electrons and how they are placed around an atom all of the elements in the same group on the periodic table (vertical column) share the same properties. If you want to learn more as to why this is the case look up more about electrons.

theyhave more neutrons and protons
Bromine is farther down the group and has more electron shells, making it an element with a lager atomic radius.
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
Fluorine , Bromine , Iodine are similar to chlorine. They are non-metals placed in group-17.
it is fatter and bigger there fore is heavier so has more protons and neutrons
Since fluorine is a gas, it does not have malleability.
The reason why fluorine has a higher ionization energy level than oxygen is because it is closer to the nucleus than is oxygen, therefore, it will take more energy to pull electrons from the nucleus.
The thing that makes fluorine so reactive is its electronegativity.

Fluorine is the most reactive element period. So, it is therefore more reactive than carbon. However, as carbon forms the basis of organic molecules, people come across its compounds more often.
Refering to modern Peridic Table gas which is molecule are fluorine, chlorine, Bromine, Iodine and Astatine.
